AI Technical Summary

Benefits of technology

The composition delivers sustained hydration and shine without evaporation, maintaining stick hardness and stability, and is free from the need for silicone fluids, providing effective moisturization and transfer resistance.

Problems solved by technology

The problem with conventional solid lipsticks which claim to moisturize the lips is that only small amounts of water may be incorporated therein which tends to evaporate very quickly yielding little, to no, moisturizing effect.
The addition of too much water typically results in poor stick structure and payoff.

Abstract

An emulsion lip composition, in solid or stick form, comprising: (a) a reaction product of (i) at least one polyamine with (ii) an oil-soluble polar modified polymer comprising at least one C2-C20 monomer; (b) water; (c) at least one non-volatile solvent; and (d) at least one colorant; and a method of using thereof.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to a novel moisturizing lip composition. More particularly, the present invention relates to an emulsion lip composition, such as a lipstick or lip gloss, capable of moisturizing lips due to the presence of a significant amount of water and oil contained therein and providing improved shine.DISCUSSION OF THE BACKGROUND[0002]The problem with conventional solid lipsticks which claim to moisturize the lips is that only small amounts of water may be incorporated therein which tends to evaporate very quickly yielding little, to no, moisturizing effect. The addition of too much water typically results in poor stick structure and payoff. Moreover, these types of conventional solid moisturizing lipsticks require the use of surfactants in order to form the emulsion. Finally, in order to make a solid lipstick product which possesses transfer resistance properties, silicone resins are employed in order to achieve this property...
